Update 4/11: There's a great post over on qz.com with an update on which sites were affected (with before/after lists) and what action should be taken. Key is to not bother updating passwords until the site has been fixed. Link: http://qz.com/197258/t/60189
I just finished changing alot of passwords. <phew>
Please take some time TODAY to read this brief post and change passwords for services that were affected by the Heartbleed Bug but have been fixed already.
